Snail ID Please

New Member

Was at the lfs today. I wanted a couple more nerite snails (just love these snails). I told them what I wanted, was looking at the fish while they got them ready, then I headed for home. When I went to take them out of the bag I discovered that one of them is not a nerite. I have no idea what it is as I am new to snails and only had nerite's (other than the little snails I feed to my puffer).
